4 link ?

New to this forum but not to jeeps. I have a cj7 and am wanting to do a 4 link conversion on front and back...What would everyone suggest going with for ride, do you think some air shocks or coil springs would be better? I do about 50/50 driving between on road and off. Im thinking strongly about air shocks in the front but not sure about rear. I know springs would be cheaper, but is that my only advantage? are there any disadvantages to the air shocks for DD?

Thanks for any input

I've been inclined to say that if you aren't trailering it to the trailhead, go with coils. That way, if the shock fails, you can remove it and still drive home. Sure, it'll be a bit bumpier, but you'll still drive. Lose an air shock and you are up the creek, I believe.

this is true, but how likely is an air shock to fail?


IMO best of both worlds would be Coil overs.

Not likely, but it's piece of mind to my, I guess. I agree coilovers are the way to go, though.

Just curious as to why you're wanting to go with a link suspension? Is it just for a smoother ride?.. more flex? both?

I think I'd either use coilovers if the budget allows. If it doesn't, I'd probably go with something like TJ coils.

im wanting to go with 4 link bcuz of better ride and smoother flexing, also just wanting to do something different than a leaf build. Ive looked at some prices and i think i can get some air shocks for around less than $300 per corner, coil overs seem to be more expensive. Some tj springs are in more my price range but im not sure how i would do the coil bucket on front axle, with having full size axles.

Thought about going with tj springs on back and coilovers up front....How does everyone like that set up? Is there much advantage with going coilover/air shock on back vurses tj spring?

Thanks for the input

Coil buckets on full width axles shouldn't be any different to mount than OEM axles.

Coilovers will clean up much easier making for less obstructions during high articulation and is why most will use them up front first, with all the steering junk in the way. A well made air shock and coils will do nearly the same thing but is just harder to accomplish. One thing I really like about coilovers and is one reason why prerunners use them are the combination springs they can use. For instance, one spring will allow for a soft 10" of travel, the next spring on top will be stiffer for the remainder 6 inches. This makes for really smooth landing while jumping, without bottoming out, and destroying the air/hydralic bumpstops. If you have the money, I would do coilovers, dont have to worry about spring mounts and retainers. They can take a effort to tune though and will need limit straps. If anything go with coilovers up front and coils in the rear. Most of the time you will have to cut into the cab to get good travel with coilovers in the rear and is why Jeeps dont do it a lot like the prerunner crowd, who usually end up with a cut up bed in the back.

I like 3 link up front and triangulated 4 link in the back, pretty easy setup to custom make that way.
